Various flame, fire detection

Module Features:One can detect a flame or in a 760 nanometer wavelength of ~ 1100 nm range of the light, lighter flame test distance of 80cm, for the greater flame, the farther the distance test2, the detection angle of 60 degrees or so, particularly sensitive to the flame spectrum3, sensitivity adjustable (shown in blue digital potentiometer adjustment)4, the comparator output signal clean, good waveform, driving ability, more than 15mA5, with adjustable precision potentiometer sensitivity adjustment6, the working voltage of 3.3V-5V7, the output format: digital switching outputs (0 and 1)8, a fixed bolt holes for easy installation9, small plates PCB Size: 3.2cm x 1.4cm10, using a wide voltage LM393 comparator

Module for use:1, the flame sensor flame most sensitive to ordinary light is also a rection, generally used as a flame alarm purposes.2, a small plate output interface can be directly connected to the microcontroller IO port3, with the flame sensor to maintain a certain distance, so as not to damage the sensor temperature, the flame of a lighter test distance 80cm, for the greater flame, the farther the distance test
